摘要
本试验研究了在断奶应激模式下,APS的添加对断奶仔猪免疫功能及腹泻指标的影响。结果表明:①APS的添加能显著提高断奶后仔猪的免疫功能。与对照II组相比,在断奶后第7、14天淋巴细胞百分数分别增加了7.7%(P>0.05)、18.2%(P>0.05);中性粒细胞百分数分别减少了15.2%(P>0.05)、28.6%(P>0.05);断奶仔猪的SRBC抗体效价分别提高0.47、1.49(P<0.05)个滴度;单核细胞增殖率分别提高11%(P>0.05)、25%(P<0.05)。②腹泻率在3组间差异不显著,APS添加组腹泻频率明显低于对照II组(P<0.05),与对照I组相比,差异不显著(P>0.05)。
The experiment studied the effects of astragalus polysaccharides of Huang Qi（APS） on the weaning piglets＇ immunofunctions. The results showed as follows： （1）The addition of APS can increase the function of weaning piglets, compared with control group Ⅱ at 7 and 14 days after weaning, the percentage of lymphocyte in experiment group increased by 7.7% （P〉0.05）and 18.2% （P〉0.05）respectively; the percentage of neutrophil in experiment group decreased by 15.2 （P〉0.05）and 28.6% （P〉0.05）. The SRBC antibody titers of the weaning piglets in the experiment group Ⅱ were higher than those of control group Ⅱ by 0.47Log2 and 1.49Log2 （P〈0.05）respectively. The mononuclear transformation in experiment group were higher than control group Ⅱ by 11% （P〉0.05）, 25% （P〈0.05） respectively. （2）Fhere was no significant variation in diarrhoea rate among the three groups, but the diarrhoea frequency in experiment group was lower than that of control group Ⅱ （P〈0.05）, and no significant difference was observed when compared with the control Ⅰ group （P〉 0.05）.
